Structural device for guardrail of engineering machinery cab

Abstract

The invention discloses a construction machinery cab guardrail structure device. The device comprises a cab, both sides of the upper end of the cab are fixedly connected to lower ends of vertical plates, the middles parts of the vertical plates are provided with pull rods in a sliding mode through holes, first semi-circular grooves are formed in outer corresponding sides of the upper parts of thevertical plates, first semi-circular protrusions are arranged on the inner sides of the first semi-circular grooves, the upper sides of the outer corresponding parts of the pull rods are fixedly connected to the lower ends of square plates, and the inner corresponding ends of the lower parts of the square plates are connected to the outer corresponding ends of the upper parts of the vertical plates. A guardrail is placed between the first semi-circular grooves and second semi-circular grooves, pull plates are pulled inwards, the square plates are pressed tight against the vertical plates, theguardrail is locked, an inserting rod is inserted into a lock groove to facilitate installing the guardrail on the cab, a lock rod moves upwards, a boundary cloth is inserted into an inserting frame,the lock rod is inserted an inserting groove to penetrate through the inserting groove, and a magnetized oblique kit is inserted into an iron pressure rod, so that a fence net is installed more simplyand conveniently.

Description

technical field [0001] The invention relates to the technical field of guardrail installation, in particular to a construction machinery cab guardrail structure equipment. Background technique [0002] The protective fence on the upper part of the cab is mainly set up to protect the cab from being injured by heavy objects, and it serves the purpose of protecting the driver and the machine. [0003] The existing guardrails of new construction machinery cabs are mostly installed on both sides of the upper end of the cab by means of welding, which is complicated to install. At the same time, the protective nets are installed on the guardrails by means of binding, which is very cumbersome. Contents of the invention [0004] The object of the present invention is to provide a construction machine cab protection fence structure equipment to solve the problems raised in the above-mentioned background technology. [0005] In order to achieve the above object, the present inventio...
